hello, i am a little bit confused.
i have a arduino mega and a bluetooth modul.
there exist a special phone app that can send data to the modul and i can send data from arduino to phone without pairing.
the pairing currently does not work at phone and i get no response from the AT commands^^
(currently i play only with the arduino ide.)
if me would use ̶b̶̶4̶̶r̶̶ b4a with a ble lib i can skip(ignore) the pairing?
i just need to receive data for visualization at phone yet.

Make sure not to confuse classic Bluetooth with BLE. These are two completely different communication methods.
BLE peripherals usually do not need pairing.
thats why my toothbrush with bluetooth did not pair at phone but the producer app works. :D
yes, this bt modul (DSD TECH HM-10) is ble so i can start with b4a to fetch the data direct, thats fine. :)

the AT commands now working, OMG.

and i found your ble b4a example, thank you for this.
